dyld-headers is obsolete; please uninstall it

[noloader (Jeffrey Walton)]

I'm not sure what's going on here. I did not install the headers in question, and I don't want to remove anything installed by Macport, especially if its being used by an essential package like rsync.

The error message you received is correct. The dyld-headers port is obsolete; please uninstall it.

You will have to forgive my ignorance...

I did not install it, so its not clear to me why I should uninstall it. If its needs to be uninstalled, then why does Macports not uninstall it since it installed it?

Ping???

MacPorts never automatically removes packages without your request, and we're unlikely to start adding a special case for this port. dyld-headers was probably pulled in as a dependency of something else you installed some time back, but is now no longer required.

We may change this in the future and do a more general management of your installed packages by also automatically removing packages that you didn't request and are no longer required, but if that happens it's going to be as feature development of MacPorts itself, and not specific to a port.
